New observations from the James Webb Space Telescope back up previous findings from the Hubble telescope that contradict theoretical predictions, suggesting the standard model theorists work from ...

The atmosphere, a thin veil of molecules enveloping Earth, reaches about 20 miles (32 kilometers) above the planet's surface.

Thus, the mechanism behind this accelerated expansion is being studied with two approaches. The first assumes the existence of a new component of the Universe, dark energy, whose properties are being ...

Dark matter is one of the most debated and intriguing missing puzzle pieces of modern physics – a mysterious form of energy ...

Scientists are challenging the existence of dark energy with a new model called "timescape," which suggests the Universe's ...

The universe has always intrigued scientists with its vastness and mystery. Decades ago, in the 1990s, physicists began ...

Scientists challenge the existence of dark energy. They suggest the universe's accelerating expansion is due to uneven ...

"Dark energy is a misidentification of variations in the kinetic energy of expansion, which is not uniform in a Universe as ...

creating an illusion of accelerated expansion. The findings challenge the prevailing Lambda Cold Dark Matter (ΛCDM) model, which relies on dark energy to account for the universe's observed behavior.

This late-time acceleration was discovered in 1998 by two teams of astronomers making distance measurements using supernovas ...
